Stress & stressors

Perceived stress


Contact: Hannie Comijs

Stress is experienced when the environmental demands exceeds a person’s adaptive capacity and is associated with health and diseases such as depression and cardiovascular diseases (Cohen et al. 2007). Stress can be quantified in different ways. Stressors can be measured, for example by asking about negative life events which are experienced. The number of life events can then be used as a measure of cumulative stress. However, people might react differently to stressors and  other sources of stress such as ongoing stressors, expectations of the future, and negative events in the lives of loved ones are not included when asking about life events.

A global measure of perceived stress gives information about the amount of stress which is currently experienced in a person’s live.

Measurement instruments in LASA
In LASA the Perceived Stress Scale (PSS) is used to measure perceived stress (Cohen et al. 1983). This questionnaire measures the global levels of stress in the last month by asking to which degree persons find their lives unpredictable, uncontrollable and overloaded. In LASA the 10-item version is used. Questions are answered on a Likert scale from 0-4 from ‘never’ to ‘very often’. The scale consisted of 6 negative worded items and 4 positive worded items. For the total score the positively worded items were recoded so that higher scores indicated greater stress, the sum score ranged from 0-40. Higher scores indicate higher levels of stress.

The scale perceived stress scale includes two subscales, the perceived helplessness and the perceived self-efficacy subscale. The perceived helplessness scale consisted of the negative worded items 1,2,3,6,9,10 (ranging from 0-24) and the perceived self-efficacy scale consisted of the positive worded items 4,5,7,8 (ranging from 0-16).
